FWIW I believe scala is basically agfa apx100 bW film.

I used this film with a Scala Lab Toronto Image Works to make film positives when making enlarged negatives for Pt Pd , worked very well. TIW no longer has an official Scala process. For that matter I do not think anyone does in NAmerica. DR5 has certainly figured out how to make film positives from many film brands and speeds.
Never used them but I understand there work is great.
Very interesting that there are official Scala Labs in Europe, that I did not know.
